Abstract (en)
[origin: WO03010776A1] The invention concerns a method using at least a condenser injector (20) to provide secondary feed water to a steam generator (1) in a phase during which the temperature and the pressure of the water cooling the primary circuit (2) of the nuclear reactor is varied, between hot shut-down conditions of the nuclear reactor and conditions for starting up the cooling circuit of the reactor at shut-down. The condenser injector (20) is fed with water vapour drawn from an upper part of the steam generator (1), at a first inlet, and feed water from a storage tank (10), at a second inlet. Pressurised feed water at high temperature is supplied to the steam generator (1) through an outlet of the condenser injector (20). The steam generator (1) is fed without use of a supplementary pump for drawing feed water in the storage tank (10) and for injecting feed water in the secondary part (3) of the steam generator.
